In a statement to US news channel CBNB, Carrey said: “We must encourage more oversight by the owners of these social media platforms.

“This easy access has to be more responsibly handled. What we need now are activist investors to send a message that responsible oversight is needed. What the world needs now is capitalism with a conscience.”

In October, Facebook reported that 126 million Americans saw Russian efforts to sway the 2016 US election on its platform.

Google and Twitter have also come under increasing pressure to crack down on misinformation, fraudulent advertising and extremism on their platforms.

Facebook said in January that it was “far too slow to recognise” Russian election interference and the spread of fake news on the social networking site.

In a blog post on social networks and their influence, product manager Samidh Chakrabarti said that at its worst social media “allows people to spread misinformation and corrode democracy”.

At the beginning of the year, Mr Zuckerberg said his aim for 2018 was to “fix” the site relating to its handling of abuse and misinformation.
